Compact PCM Multiplexer

Product Introduction

The PT-50T 1005 PCM multiplexer is designed with a standard 19-inch 1U high, plug-in card structure, featuring a total of 5 slots. The power disk occupies 1 slot, the main control disk occupies 1 slot, and the service disk occupies 3 slots. All boards support hot swapping for easy maintenance and upgrades.

The main control panel includes 2 optical ports, 4 E1 channels, and 2 Ethernet service channels. The service panel slot can accommodate various types of interface boards, such as FXS (16/24 channels), FXO (16/24 channels), 4W E&M (8 channels), RS232 (16 channels), ISDN (2 channels), MAG (16 channels), hotline (16 channels), and V35 (8 channels). The PT-50T offers comprehensive network management functions and is compatible with Fengtai Communications Company’s network management protocols.
